Hey I bought a 1997 panfish that didn’t have a livewell. Been looking for a replacement mostly for the extra seat and the storage room, but to use for live bait and such. Does anyone know where I could get one 

I’m sure you could find someone who does welding/fabrication work who could make one for you.

You could make a portable one from a sturdy cooler by adding either an aerator or (better) a pump and drain to circulate fresh water in/out. You could even make one from plywood and fiberglass/ epoxy but that would probably be better as a permanent installation.

Go on to Google and type in "portable boat fish livewells" and you won't believe how many come up.  Most not cheap.

Try calling Tracker. Might be a little expensive, but I bet they would have one. I ordered some carpet from them to cover a flipping deck I built on my old P/T 185. I received it with zero problems, matched perfectly.
